Abstract
A navigation device with improved detour routing is disclosed. The navigation device is generally operable to calculate a first route to a destination utilizing a current location of the navigation device, receive a detour request from a user provided by the user functioning a single detour input once, and calculate a second detour route to the destination in response to the detour request. Such a configuration enables the user to easily and safely request additional route calculations to provide a detour around undesirable travel conditions without requiring extensive user input.
